Menadione (pronunciation: meh-nuh-dye-own) is a synthetic, water-soluble vitamin K analogue. It is also known as Vitamin K3.

Etymology

The term "Menadione" is derived from the chemical name 2-methyl-1,4-naphthoquinone. The name "Vitamin K3" is due to its classification as one of the vitamins in the K group, specifically the third one discovered.
